“…NPQ reflects the portion of excess light energy dissipated by heat radiation, which is important to prevent photoinhibition or protect the photosystem from peroxidation damage Cao 2008, Derks et al 2015). It progressively increased under drought stress (Elsheery and Cao 2008) and different salinity levels (Elsheery et al 2020b). However, in this work, the value of NPQ decreased after 42 d after flowering in both varieties.…”

“…Chl degradation and leaf yellowing are typical characteristics during green plant senescence, which are usually obvious indicators of leaf senescence. The decrease in Chl concentration could induce a reduction in net photosynthetic rate (Elsheery et al 2020b). Compared with JD74, Z1 plants exhibited marked leaf color retention, and the Chl content remained at a higher level until late maturity.…”

“…Maximum PSII efficiency, Fv/Fm, reflects the original optical energy conversion efficiency within PSII reaction centers, which is a reliable parameter to estimate the photochemical activity of PSII (Kalaji et al 2012). Moreover, the Fv/Fm value is also an important indicator in plant stress physiology (Laxman et al 2013, Sunoj et al 2016; it decreases significantly during senescence or stress (Li et al 2002, Elsheery et al 2020b. Improved Fv/Fm demonstrates the amelioration capacity of maximum photochemical efficiency of PSII under stress (Elsheery et al 2020a).…”

“…El aumento en peso se debe a la capacidad de las plantas injertadas para modificar aspectos morfológicos, fisiológicos y expresiones génicas a fin de mantener alta actividad fotosintética y estabilidad de la membrana, de tal manera que pueda tolerar la salinidad y mejorar los parámetros de crecimiento y rendimiento (Elsheery et al, 2020). No obstante, el comportamiento difiere por el tipo de portainjerto.…”

“…Considering the aforementioned biotic and abiotic constrains, emergence for better adaptation and selection as well as for reproduction of superior genotypes (e.g., through grafting or in vivo techniques) will have a significant impact in the future. Indeed, various studies nowadays focus on adaptation through grafting approaches for example cucumber salinity tolerance of cucumber ( Elsheery et al, 2020 ), while a comprehensive recent review points out the significance of grafting for disease control, productivity and fruit quality ( Belmonte-Urena et al, 2020 ). Creation through grafting of new superior genotypes will have a significant impact in order to achieve sustainable agricultural production and food security under the climatic changes which are evident nowadays.…”

Plant grafting is an ancient agricultural practice widely employed in crops such as woody fruit trees, grapes, and vegetables, in order to improve plant performance. Successful grafting requires the interaction of compatible scion and rootstock genotypes. This involves an intricate network of molecular mechanisms operating at the graft junction and associated with the development and the physiology of the scion, ultimately leading to improved agricultural characteristics such as fruit quality and increased tolerance/resistance to abiotic and biotic factors. Bidirectional transfer of molecular signals such as hormones, nutrients, proteins, and nucleic acids from the rootstock to the scion and vice versa have been well documented. In recent years, studies on rootstock-scion interactions have proposed the existence of an epigenetic component in grafting reactions. Epigenetic changes such as DNA methylation, histone modification, and the action of small RNA molecules are known to modulate chromatin architecture, leading to gene expression changes and impacting cellular function. Mobile small RNAs (siRNAs) migrating across the graft union from the rootstock to the scion and vice versa mediate modifications in the DNA methylation pattern of the recipient partner, leading to altered chromatin structure and transcriptional reprogramming. Moreover, graft-induced DNA methylation changes and gene expression shifts in the scion have been associated with variations in graft performance. If these changes are heritable they can lead to stably altered phenotypes and affect important agricultural traits, making grafting an alternative to breeding for the production of superior plants with improved traits. However, most reviews on the molecular mechanisms underlying this process comprise studies related to vegetable grafting. In this review we will provide a comprehensive presentation of the current knowledge on the epigenetic changes and transcriptional reprogramming associated with the rootstock–scion interaction focusing on woody plant species, including the recent findings arising from the employment of advanced—omics technologies as well as transgrafting methodologies and their potential exploitation for generating superior quality grafts in woody species. Furthermore, will discuss graft—induced heritable epigenetic changes leading to novel plant phenotypes and their implication to woody crop improvement for yield, quality, and stress resilience, within the context of climate change.
